Frequently asked questions
What's the difference between camelCase and PascalCase?
In camelCase the first word starts with a lowercase letter (variableName), while in PascalCase every word, including the first, starts with an uppercase letter (ClassName). Both remove spaces and punctuation between words.
When should I use snake_case or kebab-case?
snake_case (with underscores) is common for variable names in Python and databases. kebab-case (with hyphens) is common in URLs, file names, and CSS classes. The choice depends on the convention of the language or tool you're using.
What is Sentence case?
It's the capitalization used in normal sentences: only the first letter of each sentence is uppercase, with the rest of the text in lowercase, like this very text.
